CBUSHIING-MCHINE.

T all lwhom 4it may concern:

Beit lmown that we, and ALBERT SCARAMELLA, citizens of the United States, residingat New Haven, in the county of New Haven and State of Connecticut, have invented certain new and`use ful Improvements in Crushing-Machines, of

I 'which the following is a specification, refer- I ence being had therein to the accompanying drawings.

Our invention relates to new and im proved crushing machines, particularly to. that. class ofsuch machines as are'designed for crushing or pulping fruits, vegetables and the like, to separate vthe liq'uid fromthe solids. l

, It is the object of this invention, among other things, lto provide a device of this character, so designed thatit may be economically constructed, readily and' conveniently assembled and taken -down'and will produce the most efficient results, removing the very maximum amount of liqulds from the solids bperated thereon..

To these and other ends our cosists in the crushing machine having certain details of constructionl and combinations 'of parts as will be hereinafter describedand more particularly pointed out'in the claims. Y

In the drawings accompanyingfthis speciication and made part hereof and in which like numerals: of reference designate like Y.parts in 'each of the figures,A

Figure 1 is a fragmentary side view of our improved device assembled, and

Figi 2 is an end view thereof partly 4in section, the sectional parts being taken substantially upon line 2-2 of Fig. 1.

In thepractice of our invention, we pro vide abody member 1Q having a chamber 11' therein which opens into a funnel'1 2 upon one side thereof, as' is usual in meat choppers and the like. l .Y

Rotatably mounted in the .body 10 is a stub shaft 13, a portion 144the'reof being rectangular in cross section, shown hereinv as fsquare, with a collar 15 thereon. Surround ing this. shaft with its head normally in contact with one end of the chamber 11 is a cup 16 between which and the collar 15 is a coll provides means for rotating said shaft.' A

gear or other similar devlce may be sub,

- sticuted 'for the rank 18 if desired, as a ber. The number of tie bars may however be varied. Ears 21 -whichY project radially from thelhead 20 engage the dogs 22 on the 1 body memberA and provide means for detachably securing the sieve frame to the body member, a gasket 25 forming a ,liquid tight joint. Within the sieve frame is a `conical sieve 26 which abuts at its outer end againstjtheshoulder 27, upon the inside of the said frame.

Rotatably mounted within the chamber 11 .and the sieve 26 is the screw or worm 28 upon the ,outside of which is the groove 4 29, that extends from one end of the screw to the other and the depth of which decreases as it approaches the smaller end of the screw. One improved device is attached to a table, shelf or other desired place by means of the clamp 30, having a foot 31 integral therewith and opposite which is the screw 32 threaded through-the clamp.

Inoperation the fruit, vegetables or the A l like are placed into the funnel 12 from which they pass into the chamber 11 andas y they come in contact with the-rotating screw or wormv 28 are picked up bythefg'roove 29 and carried toward the outer-end thereof at the same time being crushed vand the liquid therein escaping throughV the sieve 26 into a Y receptacle (not shown) conveniently Yarranged to receive it. The solids, that is the pulp, seeds and .skins do not pass through the sieve, which isv of `such line vmesh as to prevent the'same, but continue to travel i11- thev groove 29 until theyA come to the end of the groove-adjacent to the shoulder 27,. W'hen; suliicient solids have accumulated thereat the continuous pressure of the on- .by reason thereof, away from said shoulder against-.the action of the spring 17, at which time the solids escape from the'screw and sieve andthrough the dischargercollar 23 into-a receptacle, also -conveniently arranged 'to receive. it, this latter not' being shown.

As soon Aas theresistance ofthe spring overcomes the, pressure of the solids the spring 17 returns the screw axially to its gagement between the stub shaft and screw.

No liquid can escape through thedischarge collar 23 'because ofthe engagement of the end of the screw 28 with the shoulder 27, and when the screw 28 is moved endwise away from said shoulder, the solids escaping from the screw prevent leakage of liquid therethrough, and in addition to this the tendency lof the liquid would be to iow toward the body member 10, and away from said collar, this being the largest diameter of the sieve 26.

Minor changes and alteration may be made within our invention aside from those herein suggested and we would therefore have it understood that we do not limit ourselves to the exact construction herein shown and described but claim all that falls fairly within the spirit and scope of the appended f claims. y y

Having described our invention, what we claim as new and desire to secureby Letters Patent, is:

1. In a crushing device, a body, a rotary and longitudinally movable screw therein, said body having opposite dogs extending outwardly therefrom, a sieve'frame including a head rotatably engaged with the body and having ears engageable with the dogs, a mouth, spaced longitudinal tie bars having flat uninterrupted inner faces connected at their ends to the mouth vand head, and a sieve in the frame arranged between the bars and between the yhead and mouth and engaged with said flat uninterrupted faces of the bars. v 2. In av crushing-device, a body, a rotary and longitudinally movable screw therein, a

sieve frame including a head, a mou-th, spaced longitudinal tie bars having flat uninterrupted inner faces connecting the head and mouth, and a sieve in the frame arranged betweenA the bars and-between the head and mouth, and engaged with said flat uninterrupted faces of the tie bars, said tie bars acting to assume stresses imposed by `the pulp on the mouth.

In testimony whereof, we have hereunto I aiixed our sirliatures.
